Don't really want to post photos, as it's potentially outing. Sorry, I know it would be much easier to help if I did.
I have been gradually trying to declutter and think we're nearly there with that - just a couple more areas to tackle.
I think the lighting could definitely be improved, perhaps I should look at that. We just have the main lights and some side lights on the wall, so perhaps some strategically placed lamps would help.
It's a longish room, fairly narrow. Small alcove with the TV in it. Quite a nice log burner with mantelpiece. Big window at front which gets the morning sun. French doors at back which look out onto our rather boring and somewhat neglected garden.
The room currently houses 2 sofas at one end, at right angles to each other, with the TV alcove opposite one. There is a coffee table in front of the sofas. The other end of the room houses a very compact desk and our desktop computer, printer etc, plus some shelves with files of paperwork (DH mostly works from home). There are also three tallish bookshelves - it's a bit cramped but we have nowhere else to put these, have already decluttered and got rid of a lot.
There is a door from the hall at the front of the room, next to the TV alcove. Then the other end of the room is open plan into the dining area of the kitchen.
